Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
A Delicious Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the cakes
Preheat the oven to 350°F (175°C).
In a bowl, mix flour, sugar, egg whites, butter, and whiskey until smooth.
Divide the batter into three layers and bake in cake tins until golden.
Make the icing
For the icing, boil 1 pound of sugar with 1 teacup of water for 8-10 minutes until it forms strings.
Do not stir the mixture; if it begins to crystallize, add 1 beaten egg white.
Once boiled, pour the syrup over 4 beaten egg whites and mix until it whitens.
Gradually add the prepared citron, figs, raisins, and almonds to the icing.
Beat the icing until it begins to stiffen, then spread it between and on the sides of the cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake layers together as they bake.
- Egg whites
- Set during baking to give the cake lift and structure, and whip into the icing for body.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Granulated sugar
- Sweetens the cake and helps it brown, and forms the syrup that becomes the icing.
- Raisins
- Add chewy sweetness and moisture to the icing.
The step that matters
Do not stir the sugar syrup while it boils. Stirring can trigger crystallization, making the syrup grainy. Adding a beaten egg white helps keep it smooth, and the syrup must reach the string stage so the icing sets properly.
Swap the fig
How well each one fits the dish's main ingredients (flour, sugar, egg, butter, raisin, almond):
- Vanillafits about as well
- Figthe original
- Coconutfits less well
- Peachfits less well
Fit is the average pairing score against flour, sugar, egg, butter, raisin, almond. Candidates are from the same food group and used in at least 100 recipes.
